Battery is mainly used to save files in emergency. Please always connect V1 to external power while it is in use.

Screen Viewing Angle: The screen size of this dash cam is 2.4 inches. For cost reduction, we use the common TN panel in the market that has a narrow viewing angle. If we chose to use the IPS panel to provide a wider viewing angle, then we will need to get it customized by the supplier and that will increase the device cost significantly. So to provide usage under normal circumstances, the TN panel is a better option.
